T 0 all whom, if; may con/00772,:

Be it known that l, WILLIAM L. DWYRE, of Albany, in the county ot" Linn and State of Oregon, have invented a new and uselul Improvement in Attachments lfor Pinard-Link Gar-Couplers, of which the followingI is a full, clear, and exact description.

The main object oll this invention is to pro vide a simple and ei'iicien t device for attach- 'inent tothe ordinary pin-and-link car-coupler, by which. the same can be easily set for coupling orunconpled without going between the draw-heads ol the cars to be coupled, and will couple automatically with another coupler of the saine class when said approaching coupler is adjusted for coupling.

The invention comprises various novel features ot construction and combinations of parts; and in order thatthe invention maybe inost clearly understood l will first describe in detail the inode in which the saine may be earried into eit'ect, and then point out its distinctive features in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specilieation, in which- Figure l is a side elevation ol' a pin-andlink coupler to which my invention has been applied when set .tor coupling. Fig. 2 is a front ele VYation o.' the saine. Fig. 3 is a seetional side view oi' the saine on the line a: ai, Fig. 2. Fig. #l is a cross-seetional view of the saine on the line fli/ f i/, Fig. 23.

Like letters ot' reference designate corresponding parts in the ditlerent figures oi' the drawings.

A designates the verticallyapertured drawhead, and li the coupling-pin, ot an ordiilary pin-and -linlc coupler.

ln the arrangement ol' the invention shown a hoodwlike casing, '1, is 'fitted detachabl y over and around the shank A otf the drawdiead A in such a manner that the top plate, (V, and the side plate C? ol? said easing` will bear against the corresponding parts of the shank A', while the opposite side plate, (.13, et' the casing will, except at iis front and rear ends, which also bear against the shank A', be held laterally apart from the corresponding side of the shank A', and thus Vform therebetween an upward-opening vertical recess, D. The

side plates, (l2 ol' the casing project below the shank A', and between. them is fitted a bottoni casing-plate, O1, which is provided with an eye-lug, C, proj eeting from its under side, and is held securely, but detaehably, in place by bolts E E', passed transversely through the proj ectin g lower edges of the side plates, 'l2 Ci?, and beneath the said bottoni plate, Cil, the forward bolt, E, being also passed through the eye-lug C". A slot, F, is formed in the bottom plate, C", in range of the vertical recess D and above the bolt E to receive and permit the play of the upwardextending cam-arm F of a link-lifting lever, F2, which is pivoted on the bolt Ehetween the eye-lug Cf and the side plate C3, and the lower arm, F3, ol which is bent laterally, forward, and upward, and has an upwardly-concave lin k-en gaging arm, Fi, projecting across and below the mouth of the draw-head A.

A longitudinal slot, (i, is formed in the top casing-plate, C', adjacent to the vertical re- D, the inner wall, G', of said slot being u mlercnt, as sh own7 and in sai d slot is mounted to slide a bolt, ll, havingl a beveled side to lit the undercut slot-wall Gr', and the forward end ol' which is mounted to slide loosely in and to project normallyii'rom a corresponding guide-aperture, ll', wh ich is inade through the upper lip of the drawwliead A, so that the bolt H will be pushed inward bythe draw-head ot' an approaching coupler, as indicated in Fi 3.

'lo the outer side ol the bolt ll is fixed a tappet, l, which extends downward and is mounted to slide freely in the rece s D, so as when the bolt H is retracted, as stated, to strike the cam-arm F ot' the lever F2 and canse the lever F` 1.o raise and guide the link of the meeting coupler into the draw-head A, immediately a t'ter which the tappet I will pass the cam-arm F' and allow the link-lifting lever F2 to be swung' downward out ot the way by the action of a spring, F", secured to sideV IOO and the bolt H projected forward, as before described, the top of the bolt-arm J will pass beneath the pin-arm B' and sustain the pin B in its raised position, so that when the bolt II is retracted bythe draw-head of a meeting coupler and the link thereof guided into the draw-head A, as before described, the arm J will be retracted, with the bolt H, from beneath the pin-arm B', and thus allow the same to fall and automatically couple the entered link.

The head of the coupling-pin l is supported from a light curved spring, l, attached to the top of the d raw-head A, so as to cause thepin to work vertically, and which springnormally acts to maintain the coupling-pin in the lowered or locking position.

On the outside of the casing side plate C3 is formed or fixed a lon gi tu d inal tubular guide, L, closed at both ends, and in which is mounted to slide a cylindrical block, M, from which a neck projects through a longitudinal slot in the side of the guide L, and has a rigid head in the forni of a bar, M3, which projects diagonally above and rbelow the side plate C3, and the upper end of which has a rigid lateral arm, N, arranged to strike the back of the bolt-arm J, while the lower end of the said bar also has a rigid lateral arm, N', to strike the back of the link-lifting lever F2. The arrangement is such that when the bar M3 is drawn forward its arms N and N' will strike the bolt-arm .I and the link-lifting lever I2, respectively, so that the lever F2 will be raised to permit the bolt-tappet I to pass its cam-arm F', and the bolt H, with it-s tappet I and pinsustaining arm J, then carried forward into operating position.

A chain, O, is attached to the slidin g presserbar M3, is carried forward around a pulley O', mounted on the side of the draw-head A, as shown, or tothe outer face ot' side plate C3, and then upward to a pull-rod, O9, mounted on the front of the cai-,to effect the described forward movement of the presser-bar M3 in setting to couple, and a spring', I), is interposed in the guide L between the slide-block M and the forward end of the guide to cause the immediate retraction of the presser-bar M3 after such operation.

A chain, Q, and pull-rod Q may also be connected to the coupling-pin Bv for raising the same from the roof or platform of the car before the pin-sustaining arm J is carried forward, as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the draw-head of a pin-and-link car-coupler, of a detachable hood-like casing covering the shank of the draw-head, one side plate of the casing being separated medially from the adjacent side of the shank to form a recess, a link-lifter having an arm working in said recess, and a slid- 'ing push-bolt having a tappet, also working ceases in said recess and engaging the link-lifter arm, substantially as described.

2. The combination, with a coupler drawhead, of a detachable hood-like casing covering the shank of the draw-head and its side on one side from the shank to form a vertical-9 recess, a detachable bottom plate fitted between the proj ect-ing parts of the casing and formed with a slot in range of the vertical recess and a downward-projecting eye-lug in side the said slot, a link-lifting lever mounted in said slot and in the recess thereabove, and a bolt passed transversely through the bottoni projecting parts of the casing, the. eye-lug, and the link-lifting lever, substantially as described.

4. The combination, with a coupler drawhead, of a pivotal link-lifting lever pivoted by a fixed fulcrum to move in the vertical plane in front of -the draw-head, a push-bolt proj ectible :from the front of the draw-head, and operating-connections between the pivotal link-lifting lever and the push-bolt by which the link-lifting lever is raised when the push-bolt is retracted, substantially as described.

5. The combination, with a coupler drawhead, of a swinging link-lifting lever having` a cam-arm and a push-bolt projectible from the front of the draw-head and carryingl a tappet to strike the cam-arm of and raise the link-lifting lever, and then to pass the said cam-arm and release the link-lifting lever, substantially as described.

6. The combination, with a coupler drawhead and a drop coupling-pin having' an arm proj ecting laterally from its head, of a slid- IOO IIO

ing push-bolt projectible from the front of lever, a coupling-piii-raising device, a slidingV ISO lieztd, a. block sliding` therein having a :neck proj ecting through the slot, and t presser-bar carried by said neck to work the pin-sustaixiing' devices, substantially described.

ll. The combination, with :t coupler drawhead, of L detachable hood-like casing covering the shank of the draw-head sind having t longitudinal slot provided with an undercut side wall and :L correspondingly-beveled.bolt mounted 11o slide on the said shank in the undercut slot and to be projected from the front of the draw-head, substantially :is described.
